Fmi-:PROOF PARTITION.

SPECIFICATION forming part of Letters Patent No. 683,798, dated October 1, 1901. Application filed January 19, 1901 1 Serial No. 43,938. (No model.)

To all whom, it may concern:

Be it known that I, ALBERT S. RnAvIs, a citizen of the United States, residin gat Washington, in the District of Columbia, have invented a certain new and useful Fireproof Partition, of which the following is a speciication, reference being had therein to the accompanying drawings.

This invention relates to fireproof partitions; and the object in View is to provide means for constructing the partition-walls, duc., of a building so as to rgnder the same entirely ireproof and at the same time of sufficient strength and lightness to stand all the tests and strains to which such parts of a building are ordinarily subjected.

The invention relates particularly to the construction of the studs and purlins and the manner of setting up the same and combining them one with the other, so as to form the framework of a partition which is admirably adapted to receive and form the support for the lathing, which may be of sheetmetal or other construction and to which the plaster is applied in the ordinary manner. By means of the invention hereinafter described the studs will accommodate themselves to any unevenness in the ceiling or ioor, and each stud is provided with means for attaching its opposite ends securely to the floor and ceiling. It is also practicable to combine with the studs a series of purlins or stringers and to permanently and strongly connect the purlins and studs and to arrange the sections of the purlins either in aline ment with each other or in staggered relation, as may be found more desirable.

With the above and other objects in View, the nature of which will more fully appear as the description proceeds, the invention consists in the novel construction, combina` tion, and arrangement hereinafter fully described, illustrated, and claimed.

In the accompanying drawings, Figure 1 is a side elevation of a portion of the framework of a partition-wall constructed in accordance with the present invention. Fig. 2 is a horizontal sectional view of the same. Fig. 3 is a detail perspective View of the cruciform union. Fig. 4 is a detail elevation showing anotherform of joint between the purlin-seci union.

tions and a stud. Figs. 5 and 6 are plan and edge views, respectively, of one end of a purlin-section. Figs. rland 8 are plan and edge views of the adjoining end of an adjacent or contiguous purlin-section. Fig. 9 is a detail perspective View of the stud-cap, which may also be used as astrid-base. Fig. 10 is a similar view of the stud-base, which may also be used as a cap for the stud. Fig. 11 is a cross-section through the preferred fo'rm of stud. Figs. 12, 13, 14, and 15 are similar sections showing other forms of studs. Fig. 16 is a horizontal section through a partition-Wall, showing the4 studs reversely disposed. Fig. 17 is a detail View showing the application of a wooden filler-strip to a stud to provide for securinga picture strip or rod to the studding. Fig. 18 is a detail View showing a modified construction of cruciform Fig. 19 is a detail perspective View showing means for attaching the metallic lathing to a stud or purlin.

Similar characters of reference designate corresponding parts in all figures of the drawings.

I construct the studs and purlins from strips of sheet metal, which may be of any desired width and length and which may also be of any desired gage or thickness to secure the necessary strength. In the preferred embodiment of this invention each stud 1 is composed of a single continuous strip of sheet metal, which is bent on the central longitudinal line 2 and on vother longitudinal lines 3 parallel to the line 2 and located at points equidistant from the center to form the V- shaped body portion B, as best illustrated in Fig. 11. The portions 4 of the metal at opposite sides of the bend 2 may be dared at any desired angle to each other, and the longitudinal edge portions of the strip are bent to extend in opposite directions to form the flat bearing-flanges F, against which the metal or other lathing (indicated at 5- in Fig. 1) is adapted to bear and to be secured by wires passing through and around portions of the metal lathingv and also around the stud. The lathing may, however, be connected to the studs in any other convenient manner, and it will be understood that the lathing is applied to opposite sides 4of all of the studs,

IOO

as shown in Figs. 2 and 16. In Fig. 2 the studs 1 are arranged with their body portions extending in the same direction; but, if desired, the studs may be arranged with their body portions extending in reverse or opposite directions, as shown in Fig. 16.

The preferred means for connecting the purlins and studs consists of a cruciform -union 6, comprising the rght-angularly-intersecting members Tand 8, each provided with oppositely-located upturned llanges 9, which after the purlins and studs are brought together are adapted to be bent over and securely clenched upon the flanges of the studs and purlins in the manner illustrated in Fig. 1. The purlins 10 correspond in cross-sectional shape to the studs; but in order to secure a close junction between the parts the flanges of the purlin-sections are cutaway at the points 11, so as to abut against the side edges of the flanges of the stud, While the V- shaped body portions of the purlins are extended to lap over the flanges of the stud, and their extremities are beveled, as at 12, to conform to the bevel of the body portion of the stud, as clearly shown in Figs. 1 and 2. By the construction just described the purlinsections and studs are all arranged in a cornmon plane and securely connected by the unions 6.'

In order to secure the opposite ends of the studding in place, a cap and a base are provided for each stud. The cap comprises a body portion 13,Which extends vertically and bears flatly against the flanges F of the stud, and said body is provided at opposite sides with malleable anges 14, adapted to be clenched around the ilanges F of the stud, as illustrated in Fig. 1. The upper portion of the body is bent at a right angle to form an abutment or attaching-plate 15, which may be nailed or anchored to the ceiling or brought to bear firmly against an overhead beam preparatory to applying the ceiling plaster. When the ceiling-plaster (indicated at 16) is applied, it covers the attaching-plate or abutment 15 and serves to anchor the same securelyin place after the plastering has dried. The base or footpiece is similar in construction to the cap and comprises a body portion 17, with oppositely-located side anges 18, adapted to be clenched around and upon the flanges F of the stud, the base also comprising a foot or attaching-plate 19, designed to rest upon the tile or cement floor, (indicated at 20.) The base maybe secured by a nail or other suitable fastener 21 and is further permanently secured in place by the wooden flooring 22, Which is cut to lit around the lower ends of the stud and to pass over the attaching-plate 19, as illustrated in Fig. 1.

Instead of employing the unions 6 the purlins 1O may connect directly with the studs in the manner illustrated in Fig. 4:, in which event the end of one oi the purlin-sections will be constructed as illustrated in Figs. 5 and 6, in which a part of the body portion 23 of the purlin is cut away to formrthe notches 24 to receive the flanges F of the stud, while the extremity of the body portion is beveled, as shown at 25, to conform to the bevel of the body portion of the stud. The purlin-section is also provided with the longitudinal extensions 26, forming continuations of the anges of the purlin-section and adapted to reach across the stud, as shown in Fig. 4, the extremities of the extensions 26 being bent to form clenching ears 27, which are subsequently bent around and clenched upon the' farther ilange of the stud. The contiguous end of the adjoining purlin-section also has a portion of its body cut away to form the notches 28 for the same purpose as the notches 24, hereinabove referred to, and the extremity of the body portion is also mitered or beveled, as shown at 29, to bear against the adjacent side of the body of the stud. In addition to this the said adjoining purlin-section is provided with the laterally-extending side wings 30, which project longitudinally beyond the end of the body portion, so as to reach across the stud, where they have terminal ears 31, which are intended to be bent around and clenched upon the farther flange of the stud, as clearly illustrated in Fig. 4, the ears 3l being arranged at such a distance. apart that they will straddle the adjoining purlin-section, as illustrated in the gure last referred to, while the longitudinal extensions 26 will rest upon the side Wings or extensions 30 of the adjoining purlin-section.

In order to make provision for securing a picture-supporting rod or strip to the wall, the studs l may have associated therewith filling-strips 32, of wood or other material, suitable to receive and hold nails or other fasteners by means of which picture rods or strips are usually fastened in place. The sheet metal from which the studs are formed is ordinarily thin enough to permit such nails or fasteners to penetrate the same, so that the picture rods or strips may be applied to either side of the partition-wall constructed in the manner hereinabove fully set forth.

While it is preferred to construct the studs and purlins in the manner illustrated in Fig. 1l on account of the great strength which is incident to the V-shaped body portion, the studs and purlin-sections may, however, be given a cross-sectional shapesuch as shown in Figs. l2 to 15, inclusive, Fig. l2 illustratin ga U-shaped body portion, Fig. 13 a rectangular or three-sided body portion, Fig. la a folded body portion in which the two portions of the body are folded upon each other and lie in proximal parallel relation, or a body portion may extend obliquely or diagonally between the ilanges, as shown in Fig. 15. In each of the constructions above noted, however, it will be seen that the oppositely-extending flat bearing-flanges are provided, so as to form efficient seats or rests for the metallic lathing. f'

Instead of forming the union as illustrated IOO IIO

in Fig. 3 and applying the same as shown in Fig. l said union may be constructed, as shown in Fig. 18, to fit against and embrace the V-shaped body portions of the studs and purlins as well as to bear against the oppositely-projecting flanges thereof. As shown in Fig. 1S, the union may consist of the intersecting right-angular members 7 and S',

lprovided with the V-shaped body portions 9,

which correspond with and are adapted to receive the body portions of the jointed studs and purlins,the said intersecting members being provided with oppositely-located flanges 9, which may be clenched around the flanges of the studs and purlins in thesame manner as the flanges of the first-described cruciform union. The last-described union by reason of its bent cross-sectional shape forms a stiffer and in somecases more desirable union than the one illustrated in Fig. 3, although requiring more material and being for that reason somewhat more expensive.

Instead of employing wire for securing the metallic lathing to the studs and purlins of the partition-frame resort may be had to a special clip consisting of a folded body portion 33 and oppositely-arranged holding-fingers 34, forming longitudinal extensions of the side portions of the body 33. The clip is constructed of sheet metal, so that prior to applying the lathing the fingers 34 may be bent outward at right angles, as shown in Fig. 19, and after the lathing is placed thereon the ngers may be bent up, as shown in dotted lines in said figure, so as to securely hold the lathin g in place in the manner shown in Fig. l. In order to prevent relative slipping movement between the clip and flange of the stud or purlin after the clip has been applied to said flange, both the body of the clip and the flange are correspondingly and simultaneously crimped to form positive interlocking means, as shown at 35, any suitable implement being used for producing the crimps and the crimps extending transversely of the body 33 and flange F. An efficient support and fastening device is thus provided for securely holding the metallic lathing in place.

I do not desire to be limited to the exact details of construction and arrangement hereinabove set forth and accordingly reserve the right to change, modify, or vary the construction within the scope of this invention.

Having thus described the invention, what is claimed as new, and desired to be secured by Letters Patent, is-
